Improved saw-set



UNITED STATESv PATENT iii-ricer iMPRovEo SAW-SET.

Specification forming part of Letters Patent No. 26. 155, dated November 22, 1859.

To all 107mm it may concern.-

Be it known that I, JERRED BEACH, of Freeport, in the county of Armstrong, in the State of Pennsylvania, have invented a new and Improved Saw-Set; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in a mechanical arrangement of set-screws, graduating rest-plate, guide, gage, levers, anvil, and set, the whole being arranged and constructed in the manner hereinafter described.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construct-ion and operation.

In the laccompanying` drawings, Figure l is a side view of my improved saw-set. Fig. 2 is a perspective view of the gage. The gage is held in the desired position by means of a setscrew, 5.

cis the guide, which isfurnished with a slot, g, and is secured in the proper place and position by means ofa set-screw, 4. Y

dis the graduating rest-plate, and is furnished with two hinges, which are secured to the lugs h by rivets 7.

u is a lug through which the regulatingscrew e passes, which is used for the purpose of raising or lowering the graduating restplate d.

l is the base or body of the saw-set.

fis the operating-lever, which is secured to the base l by means ot' a set-screw, l, which acts as a fulcrum for leverj'.

m is a lever to which the set j is attached. rlhe lever m has its fulcruin at 3, and is connected with leverf by a connecting-link, o,

which is secured to levers j' and m by means of a set-screw, 2, and rivet 6.

t' is the anvil,whic'h is secured in the base or body l.

k is a projection orlug by which the saw-set is held.

The operation of my improved saw-set is as follows: Having every part arranged and constructed as represented in Fig. l, with gage a, set to suit the length of the teeth of the saw, and the graduating rest-plate raised or lowered by the regulating-screw e, so as to give the desired set to the teeth, and the guide-plate c set to the thickness of the saw-blade, the saw is then placed between the graduating restplatel and guide c, with the teeth over the anvil i and under the setj, with the points of the teeth pressed or held up to the gage a. Then by pressing down on .lever f the back end of lever fm will be raised and the front end lowered, which will bring the setj in contact with the tooth resting over anvil t', and thereby give it the desired set.

Having thus described the nature, construction, and operation of my improved saw-set, what I claim as of' myinvention, and desire to securc by Letters Patent ofthe United States, 1s-

'lhe arrangement ofthe guide c with slot g, levers f and m, connecting-link o, set-screws 1, 2, 3, 4, and 5, when used in connection with the gage a, graduating rest-plate d, regulatingscrew e, anvil c', and setj, the whole being arranged and constructed substantially as herein described, for the purpose set forth.
